Epibond® 420 A Resin 100 Epibond® 420 B Hardener 40 Material temperatures should be above 18°C (65°F) when mixing. Mix the resin and hardener at the above ratio thoroughly for 2-3 minutes to achieve a uniform color. Epibond® 420 A/B is available in a 50 mL twin cartridge, and for best results should be dispensed using manual or pneumatic dispensing equipment through a suitable mixing nozzle as shown below:
